    Ive just noticed this; but when i left the car running and had the hood open, i can feel/hear pulsation in the intake. its not like a faint pulsation either; you can definantly feel the airbox/intake vibrating. anyone know what this is?

    Maybe it's the engine ingesting air in pulses like it's supposed to?

    maybe; but wouldnt that throw a check engine light? It misfired once before; and a check engine light came on when it did.
